cuse(3): Optimise small reads and writes.

2022-10-12T15:53:21Z

When doing small reads and writes use an intermediate buffer to store the data to save locking the remote process to access data.

cuse(3): Allow shared memory allocations up to, but excluding 2 GBytes.

2022-07-27T09:33:53Z

Currently the cuse(3) mmap(2) offset is split into 128 banks of 16 Mbytes. Allow cuse(3) to make allocations that span multiple banks at the expense of any fragmentation issues that may arise. Typically mmap(2) buffers are well below 16 Mbytes. This allows 8K video resolution to work using webcamd.
